iOptron iGuider Mini Guide Scope — 30 mm, 120 mm f/4
The iOptron iGuider mini guiding scope (#3361) is a compact 30 mm, 120 mm focal-length guide scope with dielectric anti-reflection-coated achromatic optics, designed for autoguiding with short to medium focal-length telescopes.
Fits iOptron mounts directly
The scope mates with iOptron CEM26, GEM28, CEM40 and GEM45 mounts without an adapter, using the two M3 holes (30 mm apart) on the side of the later 6-inch Vixen/Losmandy dual saddle. It also has a standard 19 mm finder-style dovetail, so it fits any telescope with a finder-scope slot.
Camera
The scope accepts a 1.25-inch guide camera. Paired with iOptron's iGuider 1 camera (sold separately or as the #3360 iGuider system), it gives a guiding resolution of 6.44 arcseconds per pixel.
Scope only (#3361), not the #3360 system with iGuider 1 camera. Published 200 g weight includes camera, so not stated. Direct mount needs saddle with 2xM3 holes 30 mm apart (later CEM40/GEM45).
